My front garden peonies have a thin film of 'white wash' look on them this summer; yet, the back garden peony clumps do not. Have lived in house for 15 years and this is first time seeing this.
This is powdery mildew. This article will help with that:

I have some iris and peonies I wish to move to another spot. When is the best time to do it? Can it be done now with good care?

I have moved house and inherited two very leggy, yellow peony trees. Can I cut them back, and if so, when?
Yes, they are an outdoor tree peony, approximately 7 to 8 ft high with leaves at that height. They have buds on them. The stems are very wavy and about 1inch thick. I think they were planted many years ago (the property was tenanted before I bought it and the garden neglected). I would like to keep them if possible.
I also inherited a beautiful pink peony bush and had wonderful flowers this summer. Can I cut the bush right back now before the winter. New gardener and need advice. Thank you for replying - appreciated

How tall are the peony trees now..what zone do you live in...when you say leggy are you saying there are no leaves so far up on the trees?
I am assuming this is an outdoor tree peony. You can prune them, but I would not cut the main stem of tree. How tall are they now?
How old does a Peony plant have to be before you can divide it?
It is not so much about age, but rather the size of the plant. If it is getting too large for the area it is in, then it is ready to be divided. If it has been in the ground for a few years, and you want to share with a friend, it should be big enough to divide as well.
But, I will warn you, peonies hate to be moved or divided. When you do this, it normally takes 1-3 years before they will bloom again.
If I divide my Peonies in the fall, will the divided plants have flowers in the spring?
Regardless of when you split peonies, it will take them 1-2 years before they bloom again. They really do not like to be disturbed and moving or dividing them will delay blooming.
I have accidently cut my peony's root system. What can I do? I am a newbie at plants but have a lot of well established peony bushes in my garden. A failed transport mission of one clump has ended with a very damaged root system, however. Any chance of rescue?
They should be ok, but you will likely not see blooms from them for a few years. Peonies do not like to have their roots disturbed and when they are disturbed, they stop blooming while the roots recover. Give them some bone meal to boost phosphorous, which will help them with root repairing and just take good care of them for the next year. This will help get them back on blooming track as quickly as possible.
Is there a compatible flower to plant near peonies? I planted peonies on the side of my house this past fall and am hoping to plant more flowers around them. Would hydrangea be okay to grow next to peonies, and if so, how far should I space them away from the peonies? What other flowers would be good to plant with peonies?
Many plants are ideal companions for peonies, especially other perennials. Some of these may include iris, dianthus, lily varieties, aster, rose, and hollyhock. Small shrubs, like hydrangea, will also work provided that they share the same growing conditions and are not planted too close, which could lead to overcrowding issues.
